    Development requirement: All unused language packs shall be deleted from front-end code, backend language configuration panel, translation database.<\/p>\n<\/blockquote>\n\n\n\n

    1.2 Language Pack Architecture Requirement<\/h3>\n\n\n\n

    All front-end pages add independent language pack management layer<\/strong><\/p>\n\n\n\n

      \n
    • All static text, button text, prompt text, page title, TDK copy stored in independent language JSON language packs<\/li>\n\n\n\n
    • No hard-coded text on any page<\/li>\n\n\n\n
    • Language pack path specification:<\/li>\n<\/ul>\n\n\n\n

      plaintext<\/p>\n\n\n\n

      \/langs\/zh-CN.json\n\/langs\/en.json\n\/langs\/de.json\n\/langs\/fr.json\n\/langs\/ru.json\n\/langs\/tr.json\n\/langs\/ko.json\n\/langs\/ja.json\n\/langs\/es.json\n\/langs\/pt.json\n\/langs\/ar.json\n\/langs\/hi.json\n\/langs\/th.json\n\/langs\/vi.json\n<\/code><\/pre>\n\n\n\n
        \n
      • Backend support one-click import\/export language pack for batch translation editing<\/li>\n<\/ul>\n\n\n\n
        1.3 Automatic Language Loading Rule (GEO + Time Zone Trigger)<\/h3>\n\n\n\n
          \n
        1. System automatically identify visitor IP country, region, time zone via GEO service<\/li>\n\n\n\n
        2. Match the most matching reserved language and automatically load corresponding language pack for first access<\/li>\n\n\n\n
        3. Manual language switch by user has higher priority than automatic GEO detection; system save user language selection into browser local storage<\/li>\n\n\n\n
        4. If the matched regional language is not in reserved list \u2192 default load English (en)<\/li>\n\n\n\n
        5. Arabic visitors automatically trigger HTML RTL layout switch<\/li>\n<\/ol>\n\n\n\n
          2. Currency Configuration Rules (Web + Buyer App Unified)<\/h2>\n\n\n\n
          2.1 Keep only two currencies, remove all other currency options<\/h3>\n\n\n\n
            \n
          1. USD (US Dollar)<\/li>\n\n\n\n
          2. CNY (Chinese Yuan)<\/li>\n<\/ol>\n\n\n\n
            2.2 Currency display logic<\/h3>\n\n\n\n
              \n
            1. GEO detection automatically match recommended display currency:\n
                \n
              • Visitors from overseas non-China regions: default display USD<\/li>\n\n\n\n
              • Visitors from Mainland China: default display CNY<\/li>\n<\/ul>\n<\/li>\n\n\n\n
              • Users can manually switch between USD \/ CNY; selection saved locally<\/li>\n\n\n\n
              • Real-time exchange rate conversion between USD and CNY on product price, checkout page, order detail page<\/li>\n\n\n\n
              • Google Shopping feed only output selected currency price according to region rules<\/li>\n<\/ol>\n\n\n\n
                3. VOLEMI Flutter Buyer Mobile App Language Rules (All App Pages)<\/h2>\n\n\n\n
                  \n
                1. The buyer app completely synchronizes the above 14 language list, consistent with web frontend<\/li>\n\n\n\n
                2. Flutter built-in independent i18n language package resource files, all UI text read from language packs; zero hardcode text<\/li>\n\n\n\n
                3. App first launch: obtain device location \/ IP GEO information \u2192 auto load matching language pack<\/li>\n\n\n\n
                4. User manual language switch saved in app local storage, priority higher than automatic detection<\/li>\n\n\n\n
                5. Arabic language mode: global automatic RTL layout flip for all pages<\/li>\n\n\n\n
                6. All modules effective: homepage, category, product detail, login\/register, checkout, order center, order details, AI customer service, personal center<\/li>\n<\/ol>\n\n\n\n
                  4. Admin Mobile App Language Note<\/h2>\n\n\n\n
                  Admin backend mobile app language scope can be configured separately (not affected by front buyer side language reduction requirement)<\/p>\n\n\n\n
                  5. SEO & Multilingual URL Synchronization Update<\/h2>\n\n\n\n

                  2. Remove all other unused language subdirectory routes<\/li>\n\n\n\n
                  3. Hreflang tags only output the above 14 language versions<\/li>\n\n\n\n
                  4. Each language corresponds independent sitemap XML<\/li>\n\n\n\n
                  5. Google Shopping multi-language feeds only generate for reserved languages<\/li>\n<\/ol>\n\n\n\n
                    6. Key Development Checklist (Deliver to Dev Team)<\/h2>\n\n\n\n
